If you owe back taxes in Portland, here is what changed in 2026
The IRS resumed full passport-revocation referrals under IRC §7345 for taxpayers with seriously delinquent federal balances over the inflation-adjusted threshold ($62,000 for 2026). Portland engineers at Intel Hillsboro, Nike Beaverton on H-1B status, founders with international banking, and remote workers traveling to Asia or Europe face real revocation exposure. Three Portland-specific 2026 pressure points sit on top of that: the Oregon Department of Revenue continues active assessment of the Corporate Activity Tax under ORS Chapter 317A, the 0.57% gross-receipts tax on Oregon commercial activity above $1 million; the City of Portland Revenue Division and Multnomah County are in active enforcement on the 1.5% Preschool for All tax and the 1% Metro Supportive Housing Services tax for individuals above the $125,000 (single) or $200,000 (joint) thresholds — many high earners filed federal and state returns but missed the county and Metro filings entirely; and the California Franchise Tax Board continues to pursue Portland transplants for vested-equity income sourced to California prior to the move. Acting before the IRS levy hits, the Oregon DOR Notice of Deficiency becomes final, or the Oregon Tax Court 60-day appeal window closes is materially easier than reversing any of them after the fact.

What this page covers and why Portland-specific tax representation matters
Victory Tax Lawyers, LLP is a California-licensed tax-law firm whose primary practice is federal IRS resolution. We represent Portland individuals, founders, executives, athletes, physicians, and businesses before the Internal Revenue Service, the U.S. Tax Court, and the IRS Independent Office of Appeals through a Form 2848 Power of Attorney, which is recognized in every IRS district nationwide. Federal tax practice is not constrained by state-bar admission; under 31 CFR §10.3 (Circular 230), attorneys, CPAs, and enrolled agents may represent taxpayers before the IRS regardless of the taxpayer's state of residence.
Portland tax practice has a specific shape. Oregon is one of five states with no general sales tax, but it offsets that with a graduated personal income tax that tops out at 9.9% — the third-highest top state rate in the country after California and Hawaii. The Oregon framework is codified principally in ORS §316.037 (graduated PIT rates from 4.75% to 9.9%) and ORS §317.061 (6.6% corporate income tax on income up to $1 million, 7.6% above). On top of state-level Oregon tax sit two local layers that materially change the analysis for Portland residents: the Multnomah County Preschool for All Personal Income Tax (Multnomah County Code Chapter 11.20), a 1.5% tax on individual taxable income above $125,000 (single) or $200,000 (joint) and 3% on the amount above $250,000/$400,000; and the Metro Supportive Housing Services Personal Income Tax (Metro Code Chapter 7.05), a separate 1% tax on individuals above the same $125,000/$200,000 thresholds across the seven-county Metro region. Stacked, a high-earning Portland resident faces a combined effective top marginal personal income tax of roughly 12.4% on Oregon-source compensation before federal tax even enters the calculation.
Then there is the Corporate Activity Tax under ORS Chapter 317A: a 0.57% gross-receipts tax on Oregon commercial activity above $1 million, layered on top of (not in place of) the regular corporate income tax. The CAT operates on a fundamentally different axis than federal income tax — no deduction for COGS in the federal sense, only the partial 35% subtraction for cost inputs or labor — and Portland service businesses, founders running through pass-through entities, and Oregon-sourced revenue from Washington and California businesses often misclassify the apportionment.
Where Portland diverges from other Oregon cities is the density of equity compensation, the volume of post-2020 California transplants still inside the FTB residency-audit window, and the cluster of Nike (Beaverton headquarters with global RSU and athlete-endorsement 1099 exposure), Intel (Hillsboro campus — largest Intel manufacturing site in the world, with extensive RSU, ISO, and IRC §174 R&D capitalization issues), Adidas North America, Columbia Sportswear, Tektronix, Precision Castparts, Safeway-Albertsons corporate, OHSU, Legacy Health, and Providence Health employees whose Form W-2 Box 12 V codes and 1099-B brokerage events generate audit-bait reconciliations at significant density. If your problem is federal, you do not need an attorney admitted in Oregon. You need an attorney with active U.S. Tax Court bar membership and federal-practitioner credentials under Circular 230. If your problem also involves the Oregon Tax Court, the California FTB, or the City of Portland Revenue Division, the analysis broadens but the federal IRS work remains the anchor.
Your tax rights as a Portland taxpayer
Federal taxpayer rights are codified across the Internal Revenue Code and summarized in IRS Publication 1, the Taxpayer Bill of Rights. They apply identically whether you live in the Pearl District, Northwest, Sellwood, St. Johns, Alberta, Hawthorne, Laurelhurst, the West Hills, Lake Oswego, Tigard, Beaverton, Hillsboro, or Gresham. The rights you can invoke in a tax-resolution matter:
Right to representation
Under IRC §7521(b)(2), an IRS examiner or collection officer must suspend an interview if you state you wish to consult with an authorized representative. A signed Form 2848 puts a tax attorney between you and the IRS for the remainder of the matter; the agency redirects all future correspondence through the CAF.
Right to Collection Due Process
After a Notice of Federal Tax Lien (IRC §6320) or a Final Notice of Intent to Levy (IRC §6330), you have 30 days to request a Collection Due Process hearing on Form 12153. CDP requests pause collection enforcement and preserve U.S. Tax Court review of any adverse Appeals determination.
Right to U.S. Tax Court review
A Notice of Deficiency triggers a 90-day petition window under IRC §6213(a). Filing a petition in Tax Court means you litigate without paying the deficiency first. Miss the 90 days and your only remedy becomes pay-then-sue in the U.S. District Court for the District of Oregon, Portland Division, or the U.S. Court of Federal Claims.
Right to an Offer in Compromise
Under IRC §7122, the IRS may accept less than the full liability where doubt as to collectibility, doubt as to liability, or effective tax administration justifies settlement. The offer is filed on Form 656 with Form 433-A(OIC) or 433-B(OIC) financial disclosure attached.
Right to a Collection Statute
IRC §6502 generally gives the IRS 10 years from the date of assessment to collect, after which the debt becomes uncollectible. Several events toll the period: pending OICs, bankruptcy, CDP hearings, and military deployment. Pull your IRS Account Transcripts to verify your Collection Statute Expiration Date before negotiating anything.
Oregon-specific: Oregon Tax Court appeal rights
Oregon is one of a handful of states with a dedicated tax court. The Oregon Tax Court, established under ORS Chapter 305, has two divisions: a Magistrate Division (informal, no formal rules of evidence) and a Regular Division (de novo trial). A taxpayer generally must petition the Magistrate Division first, and a Regular Division petition must be filed within 60 days of the Magistrate decision under ORS §305.560. The Oregon DOR Notice of Deficiency or Notice of Assessment must be appealed within strict statutory windows or the assessment becomes final.
How Victory Tax Lawyers helps Portland taxpayers
Offer in Compromise
We prepare and file Form 656 with the supporting financials under IRC §7122. The IRS evaluates Reasonable Collection Potential (RCP) using your monthly income net of allowable expenses plus the realizable value of assets. Portland filings often turn on equity-stake analysis — vested RSU positions in Nike, Intel, Columbia Sportswear, Adidas, Tektronix, and Precision Castparts, plus pre-IPO ISO holdings in earlier-stage Portland and Beaverton tech and biotech employers, sit awkwardly in RCP analysis. We pressure-test the math before submission so the offer survives at Appeals if intake rejects it.
Installment Agreement
Streamlined IAs (under $50,000), Non-Streamlined IAs over $50,000 with Form 433-F disclosure, and Partial Pay Installment Agreements under IRC §6159 that run only through the CSED. We pick the structure that fits the facts and the runway, not the structure the IRS Automated Collection System proposes by default.
Lien release and withdrawal
A Notice of Federal Tax Lien under IRC §6321 attaches to your Portland real estate, brokerage accounts, and personal property. We pursue release after payment, certificate of discharge for specific property (often required to close a Multnomah County home sale), subordination to allow refinancing, and withdrawal under the Fresh Start lien-withdrawal program for IAs of $25,000 or less.
Levy release
Wage levies (CP90 / LT11 series) and bank levies under IRC §6331 stop when we secure CNC status, an accepted IA, an accepted OIC, or a CDP request. Time matters: bank levies hold for 21 days before remittance under IRC §6332(c). Brokerage levies on Portland tech-equity accounts can be devastating if not released before liquidation, particularly on concentrated single-stock positions in Nike or Intel.
Audit and exam defense
Correspondence audits, office exams at the IRS TAC in the Edith Green-Wendell Wyatt Federal Building at 1220 SW 3rd Avenue, and field audits. We respond to Information Document Requests, attend the audit in your place under Form 2848, prepare the Form 4549 protest if we disagree, and take the case to the IRS Independent Office of Appeals if the examiner will not move.
Penalty abatement
First-Time Penalty Abatement administrative relief and Reasonable Cause requests under IRC §6651 and §6662. Common reasonable-cause arguments for Portland filers include the 2020-2022 pandemic disruption, the post-2020 downtown protest and business-interruption period, serious illness, broker-statement errors on equity reporting, preparer reliance subject to the United States v. Boyle limits, and good-faith reliance on guidance during the rollout years of the Preschool for All tax and the Metro SHS tax.
Twelve types of Portland tax issues we handle
Federal IRS practice areas, with Portland-specific framing where it matters.
Nike and Intel RSU audits
Nike RSU grants for senior employees and Intel Hillsboro engineer packages frequently run $150,000 to $500,000 at the cliff-vest mark; Adidas North America and Columbia Sportswear sit in the same range. The IRS reconciles Form W-2 Box 12 V codes against broker 1099-B basis and Schedule D. Double-counted basis on RSU sales is the single most common Portland audit trigger, and the Oregon DOR runs a parallel check at 9.9% plus the Multnomah and Metro layers.
ISO exercise and AMT exposure
An incentive stock option exercise creates an Alternative Minimum Tax preference under IRC §55 and the qualification rules of §422. Portland and Beaverton biotech, semiconductor, and SaaS engineers exercise-and-hold at pre-IPO employers, then face AMT on phantom income with §6662(b)(1) accuracy-penalty exposure on miscalculations. Oregon piggybacks on federal AMT for state purposes.
California departing-resident audits (and reverse)
The California FTB pursues former residents under Cal. Rev. & Tax. Code §17041 and Publication 1031's nine-factor residency test for income sourced to California after the Portland move. The reverse also runs: Oregon DOR pursues post-2020 Portland exiters who relocated to Texas, Arizona, Idaho, or Nevada under Oregon's part-year residency rules and source-of-income provisions in ORS Chapter 316.
Multnomah Preschool for All and Metro SHS
The 1.5% Multnomah County Preschool for All tax (3% above $250,000 single / $400,000 joint) and the separate 1% Metro Supportive Housing Services tax both kick in at $125,000 single / $200,000 joint. Many Portland residents filed federal and Oregon returns through TurboTax or a preparer who skipped the county-and-Metro layers entirely. The City of Portland Revenue Division administers both on behalf of Multnomah County and Metro, and is in active compliance enforcement.
Oregon Corporate Activity Tax (CAT)
The CAT under ORS Chapter 317A is a 0.57% gross-receipts tax on Oregon commercial activity above $1 million, with a 35% subtraction for cost inputs or labor (not both, taxpayer chooses). Portland service businesses, SaaS companies with Oregon customers, and out-of-state remote sellers regularly misclassify nexus and apportionment. The CAT runs in addition to the 6.6%/7.6% regular corporate income tax under ORS §317.061 — the two stack rather than substitute.
IRS audit defense
Correspondence, office, and field audits. We respond, document, and protest examination changes through the IRS Independent Office of Appeals or U.S. Tax Court in Portland.
Trust Fund Recovery Penalty
Under IRC §6672, the IRS pierces the corporate veil for unpaid payroll trust funds. Portland SaaS LLC owners, restaurant operators, and creative-agency founders frequently discover this after a venture-backed shutdown or post-2020 revenue collapse wipes the cap table. Oregon parallels run through the Oregon Department of Revenue Combined Payroll Tax program and the Oregon Employment Department on state unemployment-insurance contributions.
FBAR and offshore disclosure
Portland's foreign-born communities — Vietnamese (largest US population per capita), Hispanic, Russian and Ukrainian in outer Southeast, Somali, Chinese, and Indian populations across the Westside — plus international Nike athlete-endorsement deals and Intel cross-border work, mean FinCEN Form 114 and IRS Form 8938 issues recur. Streamlined Filing Compliance Procedures resolve good-faith nondisclosure without the willful penalty.
Real-estate §1031 and §121
Multnomah County home prices roughly doubled between 2014 and 2022. Many sellers missed the IRC §1031 identification deadline or misapplied the §121 $250K/$500K primary-residence exclusion to a former rental or accessory-dwelling-unit property. Oregon piggybacks on federal capital-gains treatment with the 9.9% top rate plus Multnomah and Metro layers.
Cannabis §280E disallowance
Oregon legalized recreational cannabis under Measure 91 (2014) and ORS Chapter 475C. Federally, IRC §280E still disallows business deductions other than COGS, generating substantial federal income-tax exposure for Portland dispensaries even when state-side operations look profitable. The Oregon CAT and 9.9% PIT pass-through layers compound the squeeze on owner-operators.
OHSU and physician 1099 income
OHSU, Legacy Health, Providence Health & Services Oregon, and Kaiser Permanente Northwest generate substantial 1099-NEC contractor and physician moonlighting income alongside W-2 employment. Self-employment tax under IRC §1401, quarterly estimates under §6654, and Oregon Schedule OR-A interaction often surprise mid-career physicians the year after they pick up locum-tenens or research-consulting work.
U.S. Tax Court petitions
Deficiency petitions filed in the Tax Court within 90 days of the Notice of Deficiency, with Portland trial sessions at the Mark O. Hatfield U.S. Courthouse, 1000 SW 3rd Avenue, Portland OR 97204.
Nine common causes of tax debt in Portland
1. Nike/Intel RSU vest withholding gap
Employer-default 22% supplemental withholding on a six- or seven-figure Nike or Intel RSU vest understates the true marginal rate — especially when stacked against the 9.9% Oregon top bracket and the 2.5% combined Multnomah and Metro layers. The April balance often arrives as a surprise after the W-2 lands and the broker 1099-B reconciles against Schedule D.
2. ISO exercise plus AMT trap
An ISO exercise creates an AMT preference under IRC §55. Beaverton and Hillsboro startup engineers exercise and hold, then watch the stock fall before sale and still owe AMT on phantom income. The IRC §53 credit recovers slowly; the cash-flow squeeze in the exercise year is immediate, and Oregon piggybacks on federal AMT for state purposes.
3. Missed Multnomah and Metro filings
A Portland resident files federal 1040 and Oregon Form OR-40 on time, then forgets the separate Multnomah County Preschool for All return and the Metro Supportive Housing Services return both administered by the City of Portland Revenue Division. Three years later the City sends a Notice of Deficiency with penalties and interest on combined 2.5% tax on income above the threshold.
4. California exit illusion
A tech worker moves from the Bay Area to Portland in 2023. The FTB issues a residency audit in 2026 claiming partial-year residency and California-source RSU income that vested before the move under FTB Pub 1031's nine-factor test. The Oregon DOR also asserts a 9.9% claim on the same income for the part-year period.
5. Portland-to-Texas exit illusion (reverse)
Post-2020 outmigration from Portland to Texas, Idaho, Nevada, and Arizona accelerated. Many former residents underestimate Oregon's part-year sourcing rules under ORS Chapter 316. The Oregon DOR pursues Oregon-source equity-comp income that vested before the move, plus any Multnomah and Metro residual on pre-move days. The relocation itself is fully legal — what creates exposure is sloppy sourcing of pre-move income.
6. Sold a Multnomah County home without §1031
Multnomah County appreciation between 2014 and 2022 was substantial. Investment-property sales without a like-kind exchange under IRC §1031 triggered surprise federal capital-gains balances plus 9.9% Oregon, and the §121 exclusion does not save an investment property or an ADU-rented home.
7. Startup payroll lapse
A Portland SaaS LLC stops depositing 941 trust funds during a fundraise gap or post-2020 revenue collapse. The IRS asserts TFRP against the founders personally under IRC §6672. The state side becomes an Oregon DOR Combined Payroll matter plus Oregon Employment Department unemployment-insurance exposure.
8. ERC clawback
Employee Retention Credit claims pushed by promoter mills are being clawed back through CP207/CP207L letters. Portland restaurants, dental practices, downtown service businesses hit hard during the 2020-2022 protest and pandemic period, dental practices, and creative agencies face the audit wave.
9. Crypto, DeFi, and 1099-DA gaps
Exchange 1099-K and 1099-MISC reports do not match the taxpayer's Schedule D. The IRS Automated Underreporter program issues a CP2000 notice for the gap, often with a six-figure proposed deficiency. Form 1099-DA arrives in 2026 under the new broker-reporting regime and tightens the reconciliation cycle materially.
Who is on the hook: eight tax-liability scenarios
Joint filers
Oregon is a common-law (non-community-property) state. Joint federal returns create joint-and-several liability under IRC §6013(d)(3); one spouse can be pursued for the full balance. Joint Oregon returns under ORS Chapter 316 follow the same joint-and-several rule. Innocent Spouse Relief under IRC §6015 is the principal escape valve federally, with a parallel Oregon innocent-spouse statute available for state-tax purposes.
Responsible persons for payroll
Trust Fund Recovery Penalty under IRC §6672 reaches anyone with check-signing authority who willfully failed to pay over withheld taxes — not just CEOs. For Portland startups and creative agencies, this often catches the head of finance or office manager along with the founder.
Oregon DOR officer liability
Unpaid Oregon withholding tax and the Oregon transit tax can attach personally to corporate officers and members who controlled payroll decisions under ORS Chapter 316 and the related withholding statutes. The Oregon DOR pursues these as personal-liability assessments after entity dissolution.
Transferee liability
IRC §6901 reaches a transferee of assets where the transfer rendered the transferor insolvent and tax debts remain unpaid. Portland family-LLC restructurings, Lake Oswego and West Hills estate transfers, and gift-tax adjacent transactions sometimes trigger this.
California source-of-income claims
Under Cal. Rev. & Tax. Code §17041 and the FTB's Publication 1031 sourcing rules, equity that vested while the taxpayer rendered services in California remains California-source on sale — even years after the Portland move. The FTB pursues these as nonresident-source claims well after the relocation looks finalized.
Nominee and alter-ego
The IRS files a nominee or alter-ego lien when assets titled in another's name actually belong to the taxpayer. Common in Portland asset-protection structures using family-LLC arrangements and irrevocable-trust transfers that lack arm's-length consideration.
Oregon Estate Tax exposure
Under ORS Chapter 118, the Oregon Estate Tax kicks in at a $1 million exemption — far below the federal $13.6M threshold. Many Portland homeowners with appreciated Multnomah County or Washington County real estate, concentrated tech or sportswear equity, and retirement accounts cross the Oregon threshold without owing federal estate tax. The personal representative is liable for filing and payment.
Estate and decedent returns
A decedent's final 1040 and Form OR-40, the estate's 1041 and Oregon Form OR-41, the federal 706 (if applicable), and the Oregon Estate Transfer Tax Return OR-706 run together. Personal liability for the executor attaches under 31 USC §3713(b) if estate distributions are made before federal tax claims are satisfied.
What resolution can look like
Debt reduced
An accepted Offer in Compromise settles the federal liability for less than the full amount. Partial Pay IAs cap the recovery at what you can pay through the CSED. Currently Not Collectible status freezes collection while a founder rebuilds runway.
Penalties abated
First-Time Penalty Abatement removes failure-to-file and failure-to-pay penalties for a clean compliance year. Reasonable-cause requests address pandemic disruption, the 2020-2022 Portland downtown disruption, serious illness, and broker-statement reporting errors on RSU and ISO transactions.
Liens and levies released
An NFTL withdraws once a streamlined IA is in place under Fresh Start. Wage and bank levies release when the underlying account moves to CNC, IA, or OIC processing. Passport certifications reverse once the debt drops below the §7345 threshold.
Outcomes vary. Past results do not guarantee future outcomes. Each tax case is unique.
Settlement ranges from the firm's case files
The following ranges come from Victory Tax Lawyers cases over the past several years and contribute to the firm's $100M+ aggregate tax-relief figure. Names and identifying facts are removed for confidentiality.
| Matter type | Original liability | Resolution | Approximate result |
|---|---|---|---|
| Installment Agreement | $138,296 | IRC §6159 streamlined IA | $25/month accepted |
| Partial Pay IA | $126,489 | IRC §6159 PPIA through CSED | $50/month accepted |
| Installment Agreement | $128,206 | IRC §6159 streamlined IA | $25/month accepted |
| Partial Pay IA | $116,451 | IRC §6159 PPIA through CSED | $50/month accepted |
| Installment Agreement | $152,296 | IRC §6159 streamlined IA | $25/month accepted |
Past results do not guarantee future outcomes. Each tax case is unique and turns on facts, asset position, monthly disposable income, IRS Allowable Living Expense tables, and the discretion of the assigned Revenue Officer or Settlement Officer. Acceptance rates for Offer in Compromise vary widely — the IRS reported a nationwide acceptance rate of roughly 30 to 40 percent in recent years.
Why a California-licensed firm represents Portland taxpayers
Federal tax practice is regulated by Treasury under 31 CFR Part 10 (Circular 230). An attorney admitted in any U.S. jurisdiction may represent any taxpayer before the IRS in any state via Form 2848 Power of Attorney. State-bar admission is a state-court question; the IRS is a federal agency, the U.S. Tax Court is a federal court of national jurisdiction, and the IRS Independent Office of Appeals is a federal administrative venue. Whether you live in the Pearl District, Northwest, Sellwood, St. Johns, Hawthorne, Lake Oswego, Tigard, Beaverton, Hillsboro, or Gresham, the federal procedural rules are identical.
Parham Khorsandi is a member of the State Bar of California (license #266658) and is admitted to practice before the United States Tax Court — admission there is national, not state-bound. Amir Boroumand (Cal Bar #269570) supplements the firm's federal practice. For Portland specifically, the California-bar credential carries real value: the FTB's departing-resident audit program reaches former Bay Area residents who relocated to Nike, Intel, Adidas, and Columbia Sportswear roles after 2020, and we appear before the FTB on these matters regularly. Few Oregon firms see Cal. Rev. & Tax. Code §17041 source-of-income disputes at any meaningful volume.
For Oregon Department of Revenue work — OR-40 deficiencies, CAT disputes, withholding-tax assessments, Multnomah Preschool for All and Metro SHS matters administered by the City of Portland Revenue Division, and Oregon Estate Tax filings — representation runs through an Oregon DOR power of attorney (Form OR-PoA). For formal contests at the Oregon Tax Court Magistrate Division or escalation to the Regular Division on a de novo trial under ORS Chapter 305, and for any matter that reaches the Oregon Court of Appeals or Oregon Supreme Court, we refer to local Oregon counsel and stay engaged on the federal side. The 100% remote workflow runs through a secure portal: document upload, signed Forms 2848 and 8821, and weekly status updates without anyone needing to drive downtown.
The seven steps of a VTL tax-resolution engagement
Free consultation
A 30-minute call with an attorney to outline the facts, the IRS, Oregon DOR, FTB, or City of Portland notices received, and the realistic resolution options.
Engagement letter
A written attorney-client agreement defines scope, fee, and authority. Federal common-law attorney-client privilege attaches from signature forward.
Form 2848 filed
Power of Attorney filed with the IRS Centralized Authorization File so all subsequent IRS notices route to the firm. Oregon DOR power filed where state matters overlap.
CAF investigation
Account Transcripts, Wage and Income Transcripts, and Record of Account pulled across all open years. CSED dates verified before any negotiation.
Strategy memo
A written analysis recommending OIC, IA, CNC, audit response, CDP, or Tax Court petition based on the financial profile and CSED runway.
Resolution filed
Forms 656, 433-A, 9423, 12153, or Tax Court Petition prepared and filed. Negotiations with Revenue Officers, Settlement Officers, or Appeals Officers handled directly.
Compliance close-out
Post-resolution monitoring: future quarterly estimates, return filings, CAT compliance, Multnomah and Metro filings, and protection against IA default. The case closes when the new pattern is stable.
Collection statute warning — federal, Oregon, and California
Under IRC §6502(a), the IRS generally has ten years from the date of assessment to collect a tax. After the Collection Statute Expiration Date, the debt becomes uncollectible by operation of law. Several events toll the CSED, including a pending Offer in Compromise (extends by the OIC pendency plus 30 days), bankruptcy filing (extends by the bankruptcy stay plus six months), a Collection Due Process hearing (extends while pending), Innocent Spouse claims, and continuous absence from the United States for six months or more.
On the Oregon side, the Department of Revenue generally has three years from the date the return was filed to assess additional Oregon tax under ORS §314.410, extended for substantial understatements and unlimited for unfiled returns or fraud. Oregon collection runs under ORS Chapter 305 with a statute that differs materially from the federal ten-year clock — warrants filed by the DOR can extend collection rights significantly. The Corporate Activity Tax under ORS Chapter 317A and the City of Portland's administration of the Multnomah Preschool for All tax and Metro SHS tax run on their own statutory schedules. Appeal windows are unforgiving: an Oregon DOR Notice of Deficiency must be appealed to the Magistrate Division of the Oregon Tax Court within 90 days, and a Regular Division petition runs 60 days from the Magistrate decision under ORS §305.560.
On the California side — the third leg for Portland transplants from the Bay Area — the FTB has a 20-year statute of limitations on collection of California income tax under Cal. Gov. Code §7172 after entry of the assessment, and a four-year statute of limitations on assessment under Cal. Rev. & Tax. Code §19057 (extended to six years for substantial omissions and unlimited for unfiled returns). The FTB collection horizon is twice the federal one. Pull every account transcript before negotiating anything; sometimes a Partial Pay Installment Agreement that runs out the federal statute is the better strategy than an offer that extends it.
Portland venue: where federal and Oregon tax matters are heard
Federal tax matters affecting Portland taxpayers proceed in federal venues. State matters that reach formal contest proceed through the Oregon Department of Revenue and on appeal through the Oregon Tax Court — a dedicated state tribunal that few other states match in form — with judicial review available in the Oregon appellate courts.
U.S. Tax Court — Portland trial sessions
The United States Tax Court hears Portland cases at the Mark O. Hatfield U.S. Courthouse, 1000 SW 3rd Avenue, Portland OR 97204. Trial sessions are scheduled on rotation throughout the year; petitioners designate Portland as the place of trial under Tax Court Rule 140.
U.S. District Court — District of Oregon, Portland Division
The U.S. District Court for the District of Oregon, Portland Division sits at 1000 SW 3rd Avenue, Portland OR 97204. Federal refund suits under IRC §7422 and criminal-tax matters proceed there.
IRS Taxpayer Assistance Center — Portland
The IRS operates a TAC at the Edith Green-Wendell Wyatt Federal Building, 1220 SW 3rd Avenue, Portland OR 97204. Appointments are scheduled through the IRS office locator or 844-545-5640.
Oregon Department of Revenue
The Oregon Department of Revenue is headquartered at 955 Center Street NE, Salem OR 97301, with a Portland field office at 800 NE Oregon Street, Portland OR 97232. The DOR administers Oregon PIT, corporate income tax, the Corporate Activity Tax, withholding, and the Oregon Estate Tax.
Oregon Tax Court
The Oregon Tax Court at 1180 SE Madison Street Suite 350, Portland OR 97214, is a dedicated state tax tribunal under ORS Chapter 305. The Magistrate Division operates informally (no formal evidence rules); the Regular Division conducts de novo trials. Appeals from the Regular Division go directly to the Oregon Supreme Court.
Multnomah County Department of Assessment & Taxation
The Multnomah County Department of Assessment & Taxation at 501 SE Hawthorne Boulevard Suite 175, Portland OR 97214, administers real and personal property tax assessment and collection. Property-tax appeals run through the county Board of Property Tax Appeals (BoPTA).
City of Portland Revenue Division
The City of Portland Revenue Division at 111 SW Columbia Street Suite 600, Portland OR 97201, administers the Portland Business License Tax, the Multnomah County Business Income Tax, the Multnomah Preschool for All Personal Income Tax, the Metro Supportive Housing Services Personal Income Tax, and the Portland Arts Tax ($35 flat per qualifying adult).
Oregon Employment Department
The Oregon Employment Department administers state unemployment-insurance tax and Paid Leave Oregon contributions for Portland employers. The Oregon Workers' Compensation Division administers workers'-comp coverage. Federal payroll tax (FICA, FUTA, withholding) is enforced by the IRS separately.
